I present, IDW Red Alert! I started with Titan's Return Breakaway. I added Steam Shield's panicking fire chief's head and Unicron's megatron cannon barrel from Shapeways. The light bar is Banjinbuban's transformers titans return police light bar from thingiverse. The missile is some Missile I found in my parts pile.
Thank you! Thank you! I tried to think of different ways to use my spare breakaway body and then Steam Shield made that head. I really wanted a good IDW Red Alert. I think I've waited the prerequisite time. It has that masterpiece function of, "It can do that one thing from that one episode!"
It does, along with the cannon. I'd have to cut up the chest to de-headmaster it. I just throw the head in the driver's seat and call it good.
